The animation is so good. Beautiful, smart*, and moving.
Watching this again, I'm less critical of John Chau than before. Sure, there's stuff to criticize--the apparent thinness of his local church commitment, his English-language "preaching" to the Sentinelese, the questionable wisdom of his entire strategy. But I'm more okay now with respecting Chau as someone who, in a flawed way, did something brave and even good. I'm more confident to pray that God would not let his death be in vain.
*I got those allusions to Apocalypse Now, Tintin, and Narnia.
